Your mission is to destroy each invading Frequons by moving the cursor on top of it. What could be easier? Except for one itty bitty detail: the Frequons are not displayed in the usual spatial domain, but in the Fourier Domain. Frequons look like colored waves. Your "self" is a wave too, with opposite polarity. Instead of manipulating some local point on the screen, you manipulate a global wave pattern. You destroy Frequons by achieving destructive interference with them.
